WebElectron–positron annihilation occurs when an electron ( e− ) and a positron ( e+ , the electron's antiparticle) collide. At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons : e− + e+ → γ + γ WebPositron (ß+) emission If the nucleus has too few neutrons, a proton will turn into a neutron and emit a fast-moving positron. This positron can be called a beta plus (β+) particle - this... WebA related type of beta decay actually decreases the atomic number of the nucleus when a proton becomes a neutron. Due to charge conservation, this type of beta decay involves the release of a charged particle called a “positron” that looks and acts like an electron but has a positive charge. bj\\u0027s angus meatballs

WebMar 3, 2024 · 7.2: Beta Decay. The beta decay is a radioactive decay in which a proton in a nucleus is converted into a neutron (or vice-versa). In the process the nucleus emits a beta particle (either an electron or a positron) and quasi-massless particle, the neutrino. Recall the mass chain and Beta decay plots of Fig. 7. The positron or antielectron is the antiparticle or the antimatter counterpart of the electron.
